In a letter voicing her concerns with recently announced plans to bring forward legislation to allow marriage equality, Sayeeda Warsi has warned of potential “unintended consequences” if the law were to change.

Baroness Warsi said that she is concerned about the move towards marriage equality, questioning whether churches and religious institutions should be given legal support in case of any “challenge” around same-sex weddings.

The government has been seen to have attempted to avoid critics by making it illegal for the Church of England and Church in Wales to perform same-sex wedding ceremonies, reported Politics.co.uk.

“What legal support will be afforded to churches and other places of worship if they’re challenged individually or as an organisation?” she asked.

“What consideration has been given to the teaching of equal marriage in schools, both faith schools and non-faith schools?”

Critics have suggested that The Tory peer’s choice of questions signalled that she was concerned about the Education Act 1996, which states the nature of marriage must be taught in schools, and therefore that equal marriage could also be taught, possibly as part of the sex education curriculum.

She had been accused by Stonewall of using homophobic language in past campaign literature, and later conceded that she regretted using such language.

As well as promising that no religious institution would be forced to perform same-sex weddings, it has insisted that teachers will have the option to refuse to teach anything they find inappropriate to their students, if it clashes with their religious background.

The results of this year’s government consultation show 53% are in favour of the introduction of equal marriage, however critics have suggested that because of the divide, the plans will see a difficult transition through the House of Commons and the House of Lords.
